struct XAtlasPackOptions
bool
bBilinear
Leave space around charts for texels that would be sampled by bilinear filtering.
bool
bBlockAlign
Align charts to 4x4 blocks. Also improves packing speed, since there are fewer possible chart locations to consider.
bool
bBruteForce
Slower, but gives the best result. If false, use random chart placement.
bool
bCreateImage
Create Atlas::image.
bool
bRotateCharts
Rotate charts to improve packing.
bool
bRotateChartsToAxis
Rotate charts to the axis of their convex hull.
uint32_t
MaxChartSize
Charts larger than this will be scaled down. 0 means no limit.
uint32_t
Padding
Number of pixels to pad charts with.
uint32_t
Resolution
If 0, generate a single atlas with texelsPerUnit determining the final resolution.
float
TexelsPerUnit
Unit to texel scale.
